    Capturing wifi traffic for fault diagnosis / usb pcap ?

    I have a wifi issue in a remote office. I notice now that when I install Wireshark on Windows it gives me an option to install USB Pcap. With the usb pcap can I capture wifi air traffic promiscuously, if I use any USB wifi adapter? I thinking of rushing out to source a 802.11abgnac USB adapter...

    Xbox one fault

    Been having a reshuffle of our media devices. Xbox and old Wii have been relegated to the spare room. so comes the problem. Xbox One worked fine yesterday, although a little slow, but new batteries in the controller seemed to help. Updated a few games… took forever. Just tried it tonight...

    Rather interesting fault finding video

    It's nice to see a real world fault-finding video that at least aims to follow a logical process. As we occasionally get posts about how to fault find I thought I'd share it. It's also realistic that there a few head scratcher moments where nothing quite makes sense, and the value of keeping...

    I am not a qualified electrician, I was employed as an electrician after my MoD electronics apprenticeship but that was 30 odd years ago. So I have basic skills and an insulation tester with a low resistance capability. This is an old installation with a new cu installed in 2014 (EICR etc...

    Does a three-pin socket used for Electrical Vehicle charging need a earth electrode or open PEN fault detection device?

    As the title says, does a three-pin socket (external) used as charging point need an earth electrode or open PEN fault? Are mode 1 and mode 2 exempt from this ? I was under the impression that anything used as EV charging point and if located externally, the installation would need to have...

    Siemens fridge thermostat fault?

    Hi all, I've been having a problem with my siemens undercounter fridge (model ku15r443gb/01 ) where the defrost time is too long, around 3-4 hours, and as a result it gets too warm inside during the defrost period, especially if the door is opened a lot. It's been particularly problematic in...

    Separate Arc fault protection devices not needed with RCD's?

    I'm looking at replacing my old switchboard with a new RCD/AFCI one. I asked the electrician who was quoting the job about Arc fault interrupters. I previously understood these were a different device from RCD's-RCD is to prevent shocks, AFI to prevent fires. I also understood there were devices...

    Liklihood of adjacent RCBO tripping due to fault on another circuit?

    Got an odd one. Supply is TPN TN-CS and all looks reasonably tidy but the circuit schedules bear little resemblance to the DB contents. I have a piece of fixed equipment that is generating intermittent faults and tripping the C16 RCBO. The circuit tests fine at 999MOhms at 500V on IR. So it's...

    Open circuit fault on ring

    What’s the Quickest method of finding exactly where the break in the ring is? It’s on the neutral conductor. Split ring and then join the line and neutral at dB and test between live and neutral at midway on both legs and narrow it down this way?
